View source: R/dmixture_lnorm_gumbel_function.R

Probability density function for a mixture distribution composed of one lognormal and one gumbel distribution. The gumbel distribution is suited to model the extreme values in a heavy-tail dataset, while the lognormal models the regular values.

  w.gumbel = 0.05
)

`x`	Input vector of values
`logmean`	Logmean parameter of the lognormal distribution
`logsd`	Logsd parameter of the lognormal distribution
`gumbel.alpha`	Location parameter of the gumbel distribution
`gumbel.scale`	Scale parameter of the gumbel distribution
`w.gumbel`	Weight of the gumbel distribution within the mixture (weight of lognormal is 1-w.gumbel)
